Unified Communications License Enforcement

Prognosis uses license enforcement with the Unified Communications product range, this is based upon the number of users in the UC environment being monitored. If Prognosis is run without the correct Prognosis product(s) license, alerts will be raised once a day after the license has been exceeded.

Unless a new valid license is provided, the following actions will take effect:

  • After 14 days the Web Application will be disabled.

  • After 28 days the Prognosis Server will shut down. This will result in data no longer being collected and subsequent data loss.

Messages regarding license degradation will also be sent to the Prognosis wvlog file.

If license degradation alerts are received, please contact your IR account manager to organize a new license to cater for the increased number of endpoint users.

System Monitoring for Unified Communications

Prognosis for Unified Communications is multi-vendor software product which is designed to provide a comprehensive monitoring and management platform for Unified Communications (UC) environments. It does this by collecting data, filtering it as required and then presenting it in a 'user-friendly' format, all in 'real-time'. Additional functions allow for data to be collected into databases for further analysis and reporting, generating alerts when predefined conditions are exceeded, and automatically running commands to rectify system problems.

Prognosis comes with a wide range of records and collectors that are used to gather a vast amount of data from a range of supported vendor products. Prognosis also comes with a selection of pre-packaged Displays that provide logical easy-to-use graphical representations of this collected data. The Displays for Unified Communications environments can be accessed through the Navigation panels and the initial All PBXs Display of the All PBXs Display for Unified Communications. In addition, this data can also be viewed through the Displays in the Prognosis Windows Client which can be accessed through the initial Unified Communications and Collaboration Central Display. Either of these provide a good starting point to begin finding your way around Prognosis.

For details see the following sections:

Prognosis can be configured to collect large amounts of data from the Avaya Aura CM, Avaya CS1000 and/or Cisco networks. The impact of what is displayed, saved in databases or monitored with thresholds needs to be understood. The pre-packaged Displays, Thresholds and Databases have been developed to minimize any impact on the network and are designed to scale to multiple PBXs and clusters. However, a number of Displays include warnings if they have the potential to adversely impact on network performance. It is recommended to only use these Displays for short durations, in order to diagnose problems that may be severely impacting the Unified Communications environment.

MOS Calculations for Unified Communications

Prognosis provides Mean Opinion Score (MOS) values for monitored calls in a VoIP environment. To do this, Prognosisuses 2 different algorithms depending on the vendor:

Microsoft

The MOS rating is determined by an IR proprietary algorithm that factors in the applicable Codec being used by each Skype call. This MOS rating is then used by visual alarms in the various Prognosis Displays.

The Codecs used include:

All Other Vendors

Prognosis uses an algorithm based on the ITU-T E Model. The MOS values produced are compared to the ITU-T E-Model for varying latency or packet loss.

MOS Definition

The quality of a call carried over a particular telephony system is ultimately a subjective determination. In other words, someone has to listen to the voice sent across the network and express an opinion as to whether it is of acceptable quality. MOS ranging from 0 (worst) to 5 (best) is one such subjective measurement of voice quality. It is based upon ratings of call quality by a number of listeners who are read test sentences over the communications circuit. The arithmetic mean of the ratings is used to determine the MOS.

E-model from ITU-T

ITU-T (Telecommunication Standardization Sector of the International Telecommunication Union) published the G.107 recommendation giving the algorithm for the E-model as the common ITU-T Transmission Rating Model. The E-Model is a tool for estimating the user satisfaction of a narrowband, handset conversation, as perceived by the listener. It is used to predict how an average user would rate the voice quality of a phone call with known characterizing transmission parameters. The E-Model calculates the transmission rating factor (R-value), using the network impairment factors. Typical network impairment factors used in VoIP cable telephony are codecs, delay, jitter and packet loss. After computing the R-value based on the impairment factors, the R-value is converted into a MOS score. This computational model can be useful to transmission planners to help ensure that users will be satisfied with end-to-end transmission performance.

ITU-T G.113 also provides extra information relating to the equipment impairment factor (Ie) and packet-lost robustness factor (Bpl).

Full details of the ITU-T recommendations can be found on the ITU web site at: http://www.itu.int/publications/default.aspx

The Prognosis model for calculating MOS follows the ITU-T E Model with default parameters set as shown in the following table:

Note that ITU has not defined the extension or technique for wideband code. Therefore, values for default parameters that correspond to G.711 are used for G.722, iLBC and OPUS calls for MOS calculations within Prognosis. Reporting using these parameters for wideband calls allows at least basic quality classifications to be carried out.

Theoretical Maximum MOS from E-Model

As described above, a set of default values for the various input parameters to E-Model are used. The only variables used for the MOS calculations are:

T – mean one-way delay

Ta – absolute delay

Tr – round-trip delay

Ppl - packet-lost probability

If all these parameters are set to zero, i.e. when there is simply no packet loss and no latency, the theoretical maximum MOS value for the various codecs are:

ITU supplies a calculator for R-factor and MOS values, which can be found here: http://www.itu.int/ITU-T/studygroups/com12/emodelv1/calcul.php. This calculator can be used to verify figures in the above tables 

Measurement of delay

Traditionally, in circuit switched networks, passive delay measures are estimated by looking for the echo reflected from the far-end hybrid. This is not possible within a VoIP network. The Prognosis model for calculating MOS estimates any passive delay as follows:

T = tenc + towtd + tdec

Tr = tenc + 2 * towtd + tdec

Ta = tenc + towtd + tdec

Where:

towtd is the one way transmission delay

tenc is the codec encoder delay set to (packetSize + 0.2*frameSize) + codecVariant

tdec is the decoding and jitter buffer delay set to (frameSize + jitter)

For the different codecs, values of codec encoder delay (tenc) for a 20ms packet size are given in the table below together with the default frame size:

Using this estimation, the main input parameters to the MOS calculation are:

  • packet size

  • jitter

  • packet loss

  • latency

These values are read from:

  • CallDetailRecord and CallDetailRecordDiagnostic tables within the CDR database of Cisco CallManager

  • RTCP packets for Avaya Aura PBX

  • SNMP Traps for Avaya CS1000 PBX

  • VoIP tickets for Alcatel-Lucent OmniPCX Enterprise Communication Server

This model only accepts packet loss from 0 - 20% and latency from 0 - 500ms which are the same boundaries set up in the ITU-T E-Model. The range of acceptable jitter is 0 - 250ms.

MOS values from ITU-T E-Model and Prognosis

With this modified E-Model implementation, analysis has been carried out to ensure that MOS values from the original ITU-T E-Model and Prognosis with various latency and packet loss values still have a tight correlation. The following tables show the results for G.711 calls with varying latency and packet loss values.

For details see the following sections:

Session Border Controllers

Session Border Controllers (SBC) are devices or applications that are used to control real-time session traffic at the signaling, call control, and packet layers as they cross borders between IP networks or between network segments. They admit sessions and, where necessary, reject sessions in order to protect the network from 'denial of service' (DoS) attacks and sudden spikes in congestion. A session is any real-time voice, video, presence, instant messaging or multimedia collaboration session using IP session-layer signaling protocols, such as SIP or H.323. In addition, SBCs may also be used to perform a range of call-control functions that help to reduce the load on other devices within the IP environment, these might include; Quality of Service (QoS) functions, policy-based routing and signaling protocol interworking.

SBC monitoring provides System Administrators easy access to see the status of each SBC device in the environment together with details of the real-time session traffic that is being processed. At present the following SBC vendor devices are supported:

  • Oracle SBCs

  • Avaya Session Border Controller for Enterprise

  • Cisco Unified Border Element (CUBE) SBCs

  • Ribbon devices

  • AudioCodes Mediant SBC models.

For details of the specific vendor models that are currently supported, please go to the Supported Products for Collaborate.

For details see the following topics:

Syslog Messages

Syslog is a widely used standard for message logging. It is used for computer management and security auditing as well as for general information, analysis and debugging messages. Syslog is supported by a wide variety of devices across multiple platforms and has become the standard logging solution on various systems.

The Prognosis SYSLOG record is used to hold the messages received by the Syslog Collector. The Syslog Collector (irsyslogcol.exe) is located within the Prognosis Monitoring server and is used to collect Syslog messages containing status and diagnostic information from monitored devices. If the environment consists of multiple Prognosis Monitoring servers, then for scalability, the collection of Syslog messages should be spread across all servers. To do this, each Prognosis Monitoring server should be set up to receive Syslog messages only for the systems being directly monitored by that server.

Prognosis uses 'Device Matching' to automatically tag messages with details of the device that they came from; i.e. Device name, Cluster name, Vendor, Type, Customer and Site. This is done automatically for some vendor devices that Prognosis is monitoring, e.g. Cisco Unified Communications Manager (CUCM), Cisco Unity Connection (CUC) and SBC. 'Device Matching' populates the SYSLOG record with this information from the following sources:

  • PrognosisNode (PNODES) record

  • CallManagerGateway (CMGATEWY) record

  • CISCODEV Configuration

  • SBC Configuration

‘Device Matching’ is only performed for the devices known to the current Prognosis Monitoring Server, i.e. if the Syslog messages from a device are sent to a different Prognosis Monitoring Server instead of the server currently monitoring the device, then automatic device matching will not be possible. Explicit specification will need to be done. As mentioned above, it is recommended that each Prognosis Monitoring Server to be set up to receive Syslog messages only for the devices being directly monitored by that server. This will ensure that device matching is carried out as well as spreading the load created by Syslog across different monitoring servers.

For other devices, the MAP-DEVICE statement in the SYSLOG Configuration can be used to manually specify the information, or overwrite the information from the automatic device matching, for each message based on the originating IP address.

If there are multiple devices associated with the same IP address, the DeviceName field will be populated with the text 'Multiple Devices Matched'. This indicates that the source of the Syslog message cannot be identified due to an IP address conflict. If the conflicting devices are from the same vendor, the Vendor field will be populated. The other fields will be reset to blank.

Syslog Messages

Syslog is a widely used standard for message logging. It is used for computer management and security auditing as well as for general information, analysis and debugging messages. Syslog is supported by a wide variety of devices across multiple platforms and has become the standard logging solution on various systems.

The Prognosis SYSLOG record is used to hold the messages received by the Syslog Collector. The Syslog Collector (irsyslogcol.exe) is located within the Prognosis Monitoring server and is used to collect Syslog messages containing status and diagnostic information from monitored devices. If the environment consists of multiple Prognosis Monitoring servers, then for scalability, the collection of Syslog messages should be spread across all servers. To do this, each Prognosis Monitoring server should be set up to receive Syslog messages only for the systems being directly monitored by that server.

Prognosis uses 'Device Matching' to automatically tag messages with details of the device that they came from; i.e. Device name, Cluster name, Vendor, Type, Customer and Site. This is done automatically for some vendor devices that Prognosis is monitoring, e.g. Cisco Unified Communications Manager (CUCM), Cisco Unity Connection (CUC) and SBC. 'Device Matching' populates the SYSLOG record with this information from the following sources:

  • PrognosisNode (PNODES) record

  • CallManagerGateway (CMGATEWY) record

  • CISCODEV Configuration

  • SBC Configuration

‘Device Matching’ is only performed for the devices known to the current Prognosis Monitoring Server, i.e. if the Syslog messages from a device are sent to a different Prognosis Monitoring Server instead of the server currently monitoring the device, then automatic device matching will not be possible. Explicit specification will need to be done. As mentioned above, it is recommended that each Prognosis Monitoring Server to be set up to receive Syslog messages only for the devices being directly monitored by that server. This will ensure that device matching is carried out as well as spreading the load created by Syslog across different monitoring servers.

For other devices, the MAP-DEVICE statement in the SYSLOG Configuration can be used to manually specify the information, or overwrite the information from the automatic device matching, for each message based on the originating IP address.

If there are multiple devices associated with the same IP address, the DeviceName field will be populated with the text 'Multiple Devices Matched'. This indicates that the source of the Syslog message cannot be identified due to an IP address conflict. If the conflicting devices are from the same vendor, the Vendor field will be populated. The other fields will be reset to blank.
